T 0 all whom 'it may eoncern :j i

Be known'that I, F. BETT- MAN'N, ateitizen, of the United States,residing at New Albany, in the county of Floyd. and State of Indiana,have inveiited new and useful Trolley-Wheel, of 'which' the following isa specification.

The invention relatcsoto improvements in' trolley Wheels.

The object of the present invention is to and to provide a simple,inexpensive and efiicientv trolley wheel, in which the parts whichcontact with the trolley Wire will be capable of rotary movementindependently of one another and also of. the hub or bearing, wherebythe friction andA wear will be i'educed to a minimum, and the trolleywheel prevented from rapidly heating.

w A further' object of the invrention is to provide a trolley wheel ofthis chaii'acter, which will enable ready'aceessl tobe liad to any ofits parts, and in which'anof the lat-tel' may be easily'replacedwhenworn'. With these and other objects iizidew, the invention consists inthe construction? and novel combination of parts hereinafter fullydescribed, illustrated in the accompanying drawing, 'and 'ointed out. inthe claims hereto appended; it 'being under-'Stood y that'variouschanges in'the form, proportion, size and minor details of construction,within the scope of the claiins, may be resorted to without departingfrom the s irit or sacrificingI any of the advantages o the -inventionIn the drawing :-F1guiJe 1 is a side ele- "vation of'4 a vtrolleywheel,` constructed in accordanoe with this invention, and partlybro'k'en away toshow the central sect-ion or pulle `-Fig. 2 is a centraltransverse sectiona view, Fig. 3 is a detail perspective view of thecentral or pulley section. Fig. 4 is a'detail perspective view of thehub.

Like numerals of reference designate corresponding parts in' all thefi'gure of the drawin'g; I

In the, accompan in drawin' in` which is illustrated the pre errdeinbodiment of the .invention, the trolley'wheel comprisesin itsconstruction a central or pulley section. 1, ,side disks 2,- and abearing hub 3 on which `-the central or pulley section is rotatablymounted. The central or 'pulley section 1 is ceive the trolley Wire 5,as clearly illustrated in Fig. 1 .of the drhwingzandi it'liazs'a'centralopening and| `is provided at="`opposite PatenteaJan.14`,:f9'18.f

sides at the opening 'with laterally projecti ing tubular bea-ringextension's uponwhich 1 the' side disks 2 are rot-atably inounted. sidedisks 2, which are provided wi-th centra-l. openings to receive thetubular extensions 6, have imperforate annu'lar f'lan-ges 7,' extendingoutwardly and. forming continuley wheel.

The hub 3, which passes through the 'central opening of the central orpulley section 1, consists of a slecve havinga central bore or opening,and is provided at one end .with an annular fiange 8, forming 'a headand providing an abutment-for both the central or pulley section and theadjacent side disk 2, the peripheral edge of the flange or head 8beingpreferably' arranged in fiush relation with the outer; face of theannular flange 7. The other end of the hub projects beyond the centralor pulley section andthe annular fl ange of the adjacent side disk, andit receives a set.;collar 9, havinga 'clamping screw 10 and adapted toretain thecent-ral or pulley section and the side disks in thtii'-asseinbled relation. The clamping screw 10,

which is mounted in a threaded perforationof the set collar,'engages the.hub and detachably secures the set collar thereon.

The hub 3 and the tubular bearing exten-` sions 6 are provided withperforationsll: and '12, adapted'to receive 'oil and graphite' forlubricating the parts' The perforations 11- and 12 ermit the lubricantto pass from the shaft not shown) to the side disk, and

.the imperforate annular flanges .7 of the latter cover the perforationsof the tubular extensions of the central section and prevent waste ofthe lubric'ant. Thehub, which.

rotates on the axle or bolt of the trolley head, forms a bearing for thecentral or pulley construction, which is capable of free rotation on thehub independently thereof,

:md the side disks are capable 'of free rotai'yl movenient on thetubular bearing extensions of the central or pulle'y section and rotateindependently Qf each other and also of the said central or pulleysection. vThis is especially -advantageous in preventin "Wear when a caris rounding ay curve.
